Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and more specifically, to a synchronous belt tensioning device for machine tool motors. Background Technology

[0002] A machine tool is a mechanical device that processes metal or other materials into parts or products of required shape, size, and surface quality through various methods such as cutting, grinding, casting, forging, welding, stamping, and extrusion. It can precisely process workpieces according to predetermined procedures and requirements to meet the precision, quality, and production efficiency requirements of different industrial sectors.

[0003] The power unit of a machine tool includes a spindle, which is connected to a motor via a synchronous belt. After a period of use, the synchronous belt needs to be tensioned. In existing technology, the distance between the motor and the spindle is adjusted by adding an additional adjustment device to tension the synchronous belt. However, this method is structurally complex, increasing the size and weight of the equipment, as well as manufacturing and maintenance costs. Therefore, there is an urgent need for a simple, low-cost synchronous belt tensioning device for machine tool motors that achieves convenient tension adjustment of the synchronous belt through mechanical structure optimization.

The upper side wall of the slide block has an adjustment screw hole, in which an adjustment bolt is installed. The top of the adjustment bolt abuts against the bottom of the drive motor.

[0008] Furthermore, the motor bracket consists of a fixed plate and an adjusting plate, which are perpendicular to each other. The elongated hole is opened on the adjusting plate, and the drive motor is installed on the rear side of the adjusting plate. The fixed plate is fixedly installed on the upper side wall of the slide block by screws.

[0009] Furthermore, the fixing plate and the adjusting plate are provided with slots for accommodating pulleys and timing belts.

[0010] Furthermore, the T-shaped nut includes a sliding part and a positioning part. The front side of the sliding part is the positioning part. The width of the sliding part is adapted to the width of the elongated hole. The sliding part is inserted into the elongated hole and slidably connected to it. The width of the positioning part is greater than the width of the elongated hole. The sliding part and the positioning part are an integral structure, and a threaded hole adapted to the motor bolt is opened through it.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figures 1 to 4 As shown, a machine tool motor synchronous belt 7 tensioning device includes a ram 2, inside which is a spindle 4. A milling cutter head 3 is located at the front end of the spindle 4. The milling cutter head 3 is the component that directly processes the workpiece. The rotation of the spindle 4 drives the milling cutter head 3 to rotate, thereby achieving cutting processing of the workpiece. A drive motor 1 is located on the upper side of the ram 2. The drive motor 1 is adjustablely connected to the ram 2 via a tension adjustment component 5. The design of the tension adjustment component 5 makes the connection between the drive motor 1 and the ram 2 adjustable, facilitating the adjustment of the tension of the synchronous belt 7 between the drive motor 1 and the spindle 4, ensuring the stability and accuracy of power transmission. A pulley 6 is mounted on the output end of the drive motor 1. The pulley 6 is connected to the spindle 4 via the synchronous belt 7, enabling the rotational power of the drive motor 1 to be transmitted to the spindle 4, driving the spindle 4 and the milling cutter head 3 to rotate for processing.

[0023] The tension adjustment assembly 5 includes a motor bracket 51, which is fixedly mounted on the upper side wall of the slide ram 2 by screws. The motor bracket 51 has four elongated holes 53 arranged in an array, and the length direction of the elongated holes 53 is perpendicular to the upper side wall of the slide ram 2. A T-shaped nut 54 is slidably installed in the elongated holes 53. The drive motor 1 has four motor bolts 52, which correspond to the four elongated holes 53. The motor bolts 52 pass through the elongated holes 53 and are threadedly connected to the T-shaped nuts 54. The upper side wall of the slide ram 2 has an adjustment screw hole 57, in which an adjustment bolt 56 is installed. The top of the adjustment bolt 56 abuts against the bottom of the drive motor 1 to adjust the motor height and tension the synchronous belt 7.

[0024] When it is necessary to tighten the synchronous belt 7, the head of the adjusting bolt 56 or the screw is rotated to press against the drive motor 1, so that the drive motor 1 moves along the elongated hole 53, increasing the distance between the drive motor 1 and the slide ram 2, thereby tightening the synchronous belt 7. During the movement, the sliding part 541 of the T-nut 54 moves along the elongated hole 53, which serves as a guide.

[0025] The tension adjustment component 5 adjusts the tension of the synchronous belt 7 by machining an elongated hole 53 on the motor bracket 51, machining an adjustment threaded hole 543 on the slide ram 2, and using a T-nut 54. It can be completed with simple machining based on existing equipment, with a simple structure and low cost.

[0026] In this embodiment, the motor bracket 51 consists of a fixed plate and an adjusting plate. The fixed plate and the adjusting plate are perpendicular to each other. An elongated hole 53 is opened on the adjusting plate. The drive motor 1 is installed on the rear side of the adjusting plate. The fixed plate is fixedly installed on the upper side wall of the slide block 2 by screws.

[0027] In this embodiment, the fixing plate and the adjusting plate are provided with slots 55 for accommodating the pulley 6 and the timing belt 7.

[0028] In this embodiment, the T-shaped nut 54 includes a sliding part 541 and a positioning part 542. The front side of the sliding part 541 is the positioning part 542. The width of the sliding part 541 is adapted to the width of the elongated hole 53. The sliding part 541 is inserted into the elongated hole 53 and slidably connected to it. The width of the positioning part 542 is greater than the width of the elongated hole 53. The sliding part 541 and the positioning part 542 are an integral structure. A threaded hole 543 adapted to the motor bolt 52 is opened through the interior. The T-shaped nut 54, together with the motor bolt 52, fixes the drive motor 1 on the adjustment plate.

[0029] It should be noted that the adjusting bolt 56 can be installed in two ways: the head can face the drive motor 1, or the screw can face the drive motor 1.

[0030] Working principle of the tensioning device for a synchronous belt of a machine tool motor:

[0031] When it is necessary to tighten the synchronous belt 7, the head of the adjusting bolt 56 or the screw is rotated to press against the drive motor 1, so that the drive motor 1 moves along the elongated hole 53, increasing the distance between the drive motor 1 and the slide ram 2, thereby tightening the synchronous belt 7. During the movement, the sliding part 541 of the T-nut 54 moves along the elongated hole 53, which serves as a guide.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
